WASHINGTON, Oct. 24 (UPI) -- The political organization of Virginia Gov. Terry McAuliffe, a Hillary Clinton ally, donated nearly $500,000 to the wife of an FBI official who helped oversee an investigation against the former secretary of state's email use -- an act Donald Trump's campaign called "deeply disturbing."

The Wall Street Journal on Sunday reported McAuliffe's political action committee donated $467,500 to the 2015 Senate campaign of Jill McCabe -- wife of Andrew McCabe, who serves as the FBI deputy director.

The Virginia Democratic Party, which McAuliffe has considerable control over, also donated an additional $207,788 to McCabe's campaign, the Wall Street Journal reported. She lost the election to incumbent Republican Dick Black.

Andrew McCabe would later help oversee the FBI's investigation into Clinton's use of a private email server, creating a potential conflict of interest.

"Last night's revelation that close Clinton ally Terry McAuliffe authorized $675,000 to the wife of a top official at the FBI, who conveniently was promoted to deputy director, and helped oversee the investigation into Clinton's secret server is deeply disturbing and calls into question the entire investigation," Jason Miller, Trump's senior communications adviser, said in a statement, The Hill reported. "The fact that this was allowed to occur shows either outright negligent behavior by the FBI or a level of corruption that is beyond belief. The FBI needs to fully address these issues as soon as possible."

McAuliffe's spokesman told the Wall Street Journal that the governor "supported Jill McCabe because he believed she would be a good state senator."

"This is a customary practice for Virginia governors," the spokesman said. "Any insinuation that his support was tied to anything other than his desire to elect candidates who would help pass his agenda is ridiculous."
